Well, you don't have to get it settled today, right? Give yourself a break. Take a few days or a few weeks to get yourself centered. Or, let him make the first move.
The thing about divorce is this. It will end. If the two of you cannot mutually agree, a judge will decide for you. It doesn't have to be endless back and forth. You get to decide how much you want to negotiate and when your done negotiating. It's good if you can reach an agreement, but it's not the end of the world if you don't.
Now forget about it for awhile and go do something fun this weekend!
